What is copy_to_backup?
copy_to_backup is a free software that copies files into the "backup" subdirectory, and appends date and time stamp to the copied files. For instance, running:
copy_to_backup programs/settings.iniwill copy file programs/settings.ini to programs/backup/settings_2005-08-02_23-16-15.ini. Thus, there can be many copies (versions) of the same file in the "backup" subdirectory, all sorted by time (poor man's version control / CSV).
The script is written in Ruby. If you don't have Ruby installed, use copy_to_backup.exe executable created by rubyscript2exe. Ruby can downloaded from http://www.ruby-lang.org/en/, http://www.ruby-lang.org/en/download.html or http://www.rubycentral.com/.
